In 'Thor,' that was my own hair. I grew it out. But I have naturally curly, blonde hair, so I'll never look like that. By the time I got to 'The Avengers,' I had come off two other films, which required me to have it very short. So I dyed it again and it was long enough to use a part of my hairline.

I did a production of 'Journey's End,' an RC Sherriff play about World War I, at the Edinburgh Festival. I was 18 and it was the first time that people I knew and loved and respected came up to me after the show and said, 'You know, you could really do this if you wanted to.'

I have a little office in my house and it is an absolute pigsty but I know exactly where everything is and there are little things stuck all over the walls, and papers in in-trays and files I have saved on my computer and playlists I have made on my iTunes - things that take me to a place that I think is appropriate.

An ant has no quarrel with a boot.

All acting is an act of imagination. You are simply conjuring up imaginary circumstances in your mind and responding truthfully to them.

I try not to make plans. God always laughs at your plans. I’m going to keep the door open, and keep the page blank, and see what gets painted upon it.

I am an optimist... I choose to be. There is a lot of darkness in our world, there is a lot of pain and you can choose to see that or you can choose to see the joy. If you try to respond positively to the world, you will spend your time better.
